What is polyethylene terephthalate glycol-modified plastic?
Polyethylene terephthalate is made from terephthalic acid and ethylene glycol. You can modify the plastic properties by adding another glycol such as cyclohexane dimethanol in place of ethylene glycol. The properties of the plastic will be different due to the difference in size in the molecules. The polymer melting temperature will be lower since the modification of the backbone with a different sized molecule interferes with the structure of the polymer.
What are the various uses for polyethylene glycol?
Polyethylene glycol is most commonly found in skin cremes and other beauty products. It is also found in lotions as it has many anti-aging properties.
What is upstream data?
Upstream data is data from process units upstream of whatever unit you are concerned with. Usually this includes such properties as temperature, pressure, density, composition, enthalpy, heat capacity, etc.
What is the meaning of Brent oil?
Brent crude oil is a "benchmark crude" oil agreed upon by various suppliers and traders of crude oil. Other crude oils are often priced based on the agreed upon benchmark crude which has a particular set of properties.
How do you manually add glycol to a commercial hot water system?
Pump it in while it is circulating and continually test the freeze point of the mix. If you make it too thick the solution will lose it`s heat transfer properties reducing system capacity. +10F is usually ok.
